hi,
how's it all going?
i was wondering how the following can be done using asp .NET 5?

  1. Hello http
  2. Hello json
  3. Hello dynamic object (are inferred classes possible from json? or do i need to provide a generic one?)
  4. Hello dynamically loaded method -- retrieved from memory||disc||dll||cs
  5. asyncMethod(object) --> result
  6. ReturnViaHttp(JSON.stringify(result)) // goodbye json

any links/docs/samples that could
help me implement this would be great

thanks

i don't know or particularly like python, but i'm working thru the various languages, and doing the same task (as above) it took me half a day to write the following in python, and in powershell ~ #770 and vert.x #787 these three posts are all the same issue just stated in different ways
